Sometimes I get a slight headache after dyeing my hair. What could be causing this?Updated a month ago
Headaches can occur when the weight of the dye presses on the cervical spine. In this case, it is advisable to lie down or lean back during the application time to relieve the spine.
In addition, especially during longer application times, a slight “muscle ache” can develop in the hair roots, which then manifests itself as a headache. Therefore, the recommended application times should not be significantly extended.
